patch 9.1.1935: filetype: not all Erlang files are recognized

Problem:  filetype: not all Erlang files are recognized
Solution: Detect *.app.src and rebar.config files as erlang filetype
          (John Parise).

*.app.src files contain Erlang application definitions. (There are also
*.app files, which are similar but more often build artifacts, and that
file extension is too ambiguous to be recognized by default.)

Reference:
- https://www.erlang.org/doc/system/applications.html

Rebar is the Erlang build tool. rebar.config uses Erlang syntax.
